The red fir (Abies magnifica) belongs to Pinaceae (the Pine family). It is a tall evergreen tree that is native to southwest Oregon and California in the United States. This tree grows in mountains at 1,400-2,700 m elevation, and it can reach 40-60 m in height and about 2 m in diameter. The crown is narrow conic. The bark on young trees is smooth, grey, and with resin blisters, becoming orange-red, rough and fissured on old trees. The leaves are needle-like, 2-3.5 cm long, glaucous blue-green above and below with strong stomatal bands, and an acute tip. They are arranged spirally on the twig. The cones are erect, 9–21 cm long, yellow-green, ripening brown and disintegrating to release the winged seeds in fall. The wood is used for general structural purposes and paper manufacture. It is also a popular Christmas tree.
